ISWIVEL-LOOM.

SPECIFICATION forming part of Letters Patent No. 745,538, dated December 1, 1903.

Application filed January 17, 1962n Serial No. 90,134. (No model.)

My invention relates to swivel-looms, and.

particularlyto means in connection therewith for spreading the figures forming the pattern of woven fabrics, disposing of the same, throughout the surface of the goods being woven when and where desired and while the loom is in operation.

It is not new, of course, for either plain swivel or box looms .to weave a figure or pat:

tern at regular intervals or continuously; but said figure or pattern appears in the goods in a straight line or in perfect alinement, the successive figures made by any particular swivel-shuttle occupying alternately the same relative position in the cloth as the preceding figures made by said shuttle.

The object'of'my invention is to provide a means for automatically scattering said figu res throughout the cloth whenever and wherever it is desired to do soin other words, to provide a swivel-loom that will weave a continuous pattern in an oblique or zigzag direction in a wavy manner or scatter separate and distinct figures'throughout the face of the goods when and where desired, to'do it automatically without interfering with the operation of the loom without regard to the number of ground-shuttles being used, and to enable any given swivel-shuttle to repeat the figure it is weaving wherever desired at irregular or regular intervals, so that it will not appear twice in succession in the same relative position in the cloth. For instance, a' certain swivel-shuttle may be weaving a diamond (white) on a blue ground, the sec ond diamond may be to the left of and above the first, the third to the left of and above the second, the fourth to the right of and above the third, the fifth to the right of and above the fourth, the sixth to the left of and above the fifth, and the seventh to the left of and above the sixth. The diamonds may be separate and distinct, or they may be connected by a pattern or thread which may run in a straight or a broken line, as desired. So with each of the various swivel-shuttles, with the result that my improved swivel-looin can weave a piece" of silk with a white ground so studded with blue stars that they will appear to be scattered at random.

The invention consists in various constructions and combination of parts and details, that will be fully described and set forth hereinafter and finally pointed out in the claims.

When the swivel-shuttle support is moved in either direction in its traverse, the position of the swivel-rack independently of its own is communicated to the shuttle-support, and

' it moves to the point required, and the figure is repeated.

In the accompanying drawings a means of communicating the necessary traverse motion to the swivel-shuttle support is shown; but I do not wish to limit myself to any particular means, as other means may be employed without departing from the broad scope or spirit of my invention.

Similar letters of reference indicate like parts in the various figures of the drawings, in which- Figure l is a front view of the device for communicating a traverse movement to the swivel-shuttle support, the operation thereof being indicated in dotted lines. Fig. 2 is a plan view of the same; and 3, 4, and 5 are respectively front, side, and plan views of a portion of a loom with my invention embodicd therein and showing the cords (broken off) which connect with the jacquard.

To the shuttle-support shifter-frame A is secured a stud a and stop-pins a, d a and a to limit the upward and downward movements, respectively, of the levers D and D, which are pivotally mounted on the stud a. Said levers D and D carry the pawls C and O, which engage the peculiarly-shaped teeth 12' of the ratchet-wheel B according to which ,a new position in the cloth a traverse motion of the levers is lifted by the jacquard by their cords m or 0. The said cords are secured to the openings or holes d d in the heavy ends of said levers, and each of the said levers is provided with a nose cl to control the upward movement of the pawls O and C, which turn on the screwc c. The pointed ends c of the said pawls are adapted 'to engage the ratchet-wheel B as follows: The lower stops a and a have offset portions a and a respectively, which take against the lower edges 0 c of the pawls O and C, which serve to throw the said pawls upwardlywhen the levers D and D are lowered, as shown in Fig. 1. The levers D and D when lowered rest on the straight portion of the lower stops a and a, respectively.

When the jacquard lifts the cord m, the lever D is raised, and with it its pawl O, which engages a tooth of the ratchet-wheel B causing it to turn on the stud a. The outer ends of the teeth of the ratchet-wheel are broader than they are at the base that the pawls may the better engage them. When the jacquard lifts the cord 0, the lever D and its pawl O are raised, engaging the ratchet-wheel B and turns it on the stud a, but in the opposite direction. To the ratchet-wheel B is secured the stop-wheel B and the bevel-gear B, so that when the ratchet-wheel is turned in either direction the said sprocket-wheel and the bevel-gear B are also turned in that direction.

The ratchet-wheel, stop-wheel, and bevelgear are held on the stud a b y the set-screw a and collar a An angle-lever E is mounted on a stud a which is secured to the body of the swivelshuttle-support-shifting device and is held in position by the pin a. One end of the anglelever has a curved pocket or rest 6 to support and keep in place the sprocket-wheel B when not turning. The said angle-lever is held in engagement with the sprocket-wheel by the spring 6 which is secured to the lower end of said lever at e. F represents a part of a loom-frame, G the lay, g the lay-sword, and H the swivel-shuttle support.

The bar h is secured to the lay G by the brackets 7L5 and is provided with the studs 77?, on which the swivel-shuttle support H hangs and slides laterally. Said studs 7L2 pass through the elongated openings 71. in the said shuttlesupport and are provided with means for holding the swivel-shuttle support thereon.

The swivel-rack andpinions which operate the swivel-shuttles are not shown in the drawings, it being deemed unnecessary, as the swivel-shuttle support H is shown and is adapted to carry the rack and pinions in any suitable manner, and it is therefore obvious that when the swivel-shuttle support H is antomatically moved intermittently in the direction and for the distance predetermined by the cards on the jacquard the field of operation of the swivel-rack is correspondingly changed without interfering in any way with the independent traverse motion of the swivelrack, which is communicated from another source.

A11 arm hiprovided with an elongated opening hflis secured to the swivel-shuttle support. Through this opening passes the downwardlyprojecting pin Z of a supplementary rack L, which is adapted to slide in the guides 1', secured to the bracket 2' The bracket 2' and bracket 1" form the bearings in which the shaft I is journaled. Keyed to said shaft is the bevel-gear i,which meshes with the bevel gear 13 and is turned by it in either direction, thus turning the shaft I and the gear K, secured thereto. The gear K engages the teeth of the supplementary rack L, moving it, and through it communicates a traverse motion to the swivel-shuttle support H, causing it to move in either direction, according to which of the levers is lifted by the jacquard and the distance decided by the card, which may be cut to make one or more lifts, as required.

It is obvious that the speed of the traverse motion maybe regulated by changingthe gear ing and substituting ones of different sizes.

The elongated slot 72, in the arm 7L3 permits the swivel-shuttle support to reciprocate with the lay, so that I have a swivel-shuttle support with both a reciprocatory and a traverse motion and can thus change when desired the position of the swivels h and weave the figures or patterns in any direction, practically, using many ground-shuttles, and the whole operation is automatically performed without interfering with any of the other operations of the loom.

With this description of my invention,wh at I claim, and desire to secure by Letters Patent, is
